The effect of noise channels (amplitude damping, phase damping, depolarizing and phase flip) on the behaviors of quantum correlations such as quantum discord (QD), super quantum discord (SQD) within an atom-field interaction with environments are investigated. Generation and preservation of the quantum entanglement between the qubit and field have played an important role for both fundamental quantum theories and experiments. This topic motivates us to explore the role of noise channels on quantum correlations in the Jaynes–Cummings model. Our analytical results show that the entanglement and quantum correlation dynamics is strongly related to the decoherenc strength and type of noisy channel. One purpose of this work is to answer the following question: is it possible the effects of noise channels on entangled states lead to birth of entanglement and quantum correlations or do they just have a destructive effects? We show that, the noise of all above channels do not lead to a sudden vanishing of quantum correlations. But the noise of phase flip channel reproduces initial quantum correlations. Furthermore, we find that entanglement and QD are more fragile to environmental noises than the SQD. For this reason, it seems that our results can be beneficial to deeply understanding the weak measurement and quantum correlation in quantum information resource.

不同类型噪声通道的量子相关动力学

研究了噪声通道（振幅阻尼、相位阻尼、去极化和相位翻转）对量子相关行为的影响，如与环境的原子场相互作用中的量子不和谐 (QD)、超量子不和谐 (SQD)。量子位和场之间量子纠缠的产生和保持对基础量子理论和实验都发挥了重要作用。这个主题促使我们探索噪声通道对 Jaynes-Cummings 模型中量子相关性的作用。我们的分析结果表明，纠缠和量子相关动力学与去相干强度和噪声通道的类型密切相关。这项工作的目的之一是回答以下问题：噪声通道对纠缠态的影响是否可能导致纠缠和量子相关性的诞生，或者它们只是具有破坏性影响？我们表明，上述所有通道的噪声不会导致量子相关性突然消失。但是相位翻转通道的噪声再现了初始量子相关性。此外，我们发现纠缠和 QD 比 SQD 对环境噪声更脆弱。因此，我们的结果似乎有助于深入理解量子信息资源中的弱测量和量子相关性。此外，我们发现纠缠和 QD 比 SQD 对环境噪声更脆弱。因此，我们的结果似乎有助于深入理解量子信息资源中的弱测量和量子相关性。此外，我们发现纠缠和 QD 比 SQD 对环境噪声更脆弱。因此，我们的结果似乎有助于深入理解量子信息资源中的弱测量和量子相关性。
